DJSI and sustainability investing specialist RobecoSAM named Exelon to the Dow Jones Sustainability North America Index for the eighth year in a row. The achievement distinguishes Exelon as a consistent industry leader in corporate sustainability based on a rigorous assessment of the company's economic, environmental and social performance.

Exelon was included in the index for placing among the top 20 percent of North American utility companies based on responses to more than 100 questions covering corporate governance, risk management, environmental performance, human resources development, corporate citizenship, and health and safety.

"We have an obligation to our customers, communities, employees and shareholders to operate our business in a way that is economically, environmentally and socially sustainable, and we take that responsibility very seriously," said Christopher M. Crane, president and CEO of Exelon. "This recognition validates our long-term commitment to improving sustainability performance at all levels."

Recognized for carbon emissions performance, disclosure

In addition to DJSI, CDP named Exelon to both its Global 500 Climate Disclosure Leadership Index (CDLI) and its Climate Performance Leadership Index (CPLI) for the second year in a row. No other U.S.-based utility company appeared on either the Global 500 CDLI or CPLI.

These annual indexes, based on analysis by PwC, recognize companies that lead their industries worldwide in the disclosure of information regarding their carbon footprints, climate change strategies and risk management, and in taking action on climate change mitigation, adaptation and transparency. The top 10 percent of responding companies, based on the completeness and quality of their CDP submissions, are named to the indexes. Exelon received a carbon disclosure score of 98 out of 100 in 2013 - an increase from its score of 94 in 2012 - and again fell within the "A" band, the highest performance band for emissions.

Exelon also was one of only two utility companies named to the S&P 500 CDLI and CPLI, indexes that recognize the top 10 percent of responding U.S. companies from the S&P 500.

"Companies that score highly enough to be included in the Climate Disclosure Leadership Index are responding to the call for greater corporate climate accountability," said Paul Simpson, chief executive officer of CDP. "They have demonstrated leading practice for the measurement of greenhouse gas emissions and energy use and transparency of their climate change strategy."

The foundation of Exelon's climate performance is Exelon 2020, a program that drives the company toward a goal of reducing, offsetting or displacing 17.5 million metric tons of greenhouse gas emissions per year by 2020. Exelon increased its goal from its original target of 15.7 million metric tons to account for its merger with Constellation in March 2012. As of the end of 2012, Exelon had achieved more than 89 percent of the original goal.

In addition to Exelon 2020, Exelon had numerous achievements in the area of corporate sustainability last year. For example, the company:

·Donated nearly $28 million to nonprofit organizations and provided more than 105,000 hours of employee volunteer service in its communities;

·Supported certified minority- and women-owned businesses with more than $750 million in Exelon business;

·Made substantial contributions to the economic health of its communities, paying $13.1 billion for materials, goods and services; $8.0 billion in compensation, benefits and contracting expenses; and $1.7 billion in dividends, interest and taxes; and
